Mark Wahlberg knows how to promote himself

Mark Wahlberg has gone through several attitudes about marketing himself. First we had the underwear clad Marky Mark. Then there was a period when he wanted to stay covered to distance himself from his skin baring past. Then reality struck, and he realized that skin sells movies and now he takes of his shirt as often as possible. His latest foray is a shirtless plug for a creatine shake…I wonder how much it costs to get Mark Wahlberg to plug your product.
